History of Criminological Thought

Before the eighteenth century, explanations of crime were largely theological: wrongdoing was sin, and punishment was retribution sanctioned by God or sovereign. Enlightenment thinkers challenged this framework by grounding moral and legal reasoning in human nature and social contract. Cesare Beccaria's On Crimes and Punishments (1764) was the foundational text. Beccaria argued that individuals are rational actors who pursue pleasure and avoid pain. Crime could therefore be controlled through punishment that was proportional to the harm done, certain enough to be expected, and swift enough to link act with consequence in the offender's mind. Severity beyond that threshold was both unjust and counterproductive: a harsh punishment applied inconsistently would not deter, while a moderate one applied reliably would.

Jeremy Bentham developed these ideas into his utilitarian calculus and his concept of the panopticon, a prison design intended to make surveillance constant and punishment predictable. The Classical School's influence on criminal codes was immediate and lasting. The French Code Pénal of 1791, the Napoleonic Code of 1810, and subsequent codification movements across Europe and Latin America all reflected Classical principles: defined offences, proportional penalties, and rights of the accused against arbitrary punishment. In England, Samuel Romilly and later Robert Peel drew on the same tradition to reduce the number of capital offences. In India, the Indian Penal Code 1860 (now the Bharatiya Nyaya Sanhita 2023) embedded proportionality as a structural feature of the offence-penalty schedule.

The Classical School's weakness was its silence on why some people commit crime while others, facing the same deterrent, do not. It assumed a uniform rational actor and could not account for compulsive behaviour, mental disorder, or the effect of poverty on the cost-benefit calculation. These gaps created the conditions for the Positivist School's emergence.

The Positivist School applied the methods of natural science to the study of crime and the criminal. Its founding figure, Cesare Lombroso, was an Italian army physician who conducted systematic physical measurements of soldiers and prisoners. In L'Uomo Delinquente (The Criminal Man, 1876), he proposed that a category of offenders were born criminals: biological atavists, evolutionary throwbacks to a more primitive human type, identifiable by measurable physical stigmata including asymmetric skulls, large jaws, low foreheads, and abnormal ear shapes. Lombroso later acknowledged multiple categories of criminal, including those produced by mental disorder or social circumstance, but the born criminal concept dominated public and scientific reception of his work.

Lombroso's students Enrico Ferri and Raffaele Garofalo extended the framework in different directions. Ferri introduced sociological factors alongside biological ones and was a major proponent of criminal sociology. Garofalo attempted to construct a natural definition of crime based on the universal moral sentiments he believed all civilised communities shared, a problematic concept that proved difficult to operationalise across cultures.

Despite the empirical failure of biological determinism, the Positivist School's core contribution survived: the idea that crime has causes that can be identified and addressed, that offenders may differ from non-offenders in ways that matter for intervention, and that the criminal justice system should focus on rehabilitation as well as punishment. This logic underpins parole, probation, treatment courts, and youth justice systems in jurisdictions from the United States to the UK to Australia.

In the 1920s and 1930s, sociologists at the University of Chicago transformed criminology by shifting its unit of analysis from the individual to the urban neighbourhood. Drawing on human ecology, they mapped the city as a series of concentric zones radiating outward from the central business district. The innermost residential zone, which they called the zone of transition, was characterised by deteriorating housing, frequent population turnover, poverty, and weak community institutions.

Clifford Shaw and Henry McKay's landmark 1942 study mapped juvenile delinquency rates across Chicago neighbourhoods over several decades. Their key finding was that rates remained consistently high in the zone of transition regardless of which ethnic groups lived there. As each immigrant group achieved upward mobility and moved to outer zones, their delinquency rates fell. The problem was the place, not the people. Shaw and McKay attributed this to social disorganisation: the breakdown of community institutions, informal social controls, and shared norms that normally suppress deviant behaviour.

The Chicago School produced a lasting methodological legacy in addition to its substantive findings. Ethnographic fieldwork, life-history interviews, and the careful use of official statistics and maps set a standard for empirical criminological research. The tradition directly influenced later work on community crime prevention, the broken windows hypothesis, and modern crime mapping, covered in more depth in Dark Figure of Crime and Crime Mapping.

Robert Merton's 1938 essay 'Social Structure and Anomie' drew on Durkheim's concept of anomie (normlessness) to explain a distinctly American phenomenon: high rates of property crime in a society that placed exceptional cultural emphasis on material success. Merton argued that the gap between the cultural goal of financial success and the legitimate structural means to achieve it produced strain. Individuals responded to this strain through one of several adaptations: conformity (accepting both goal and means), innovation (pursuing the goal through illegal means), ritualism (abandoning the goal but continuing to follow legitimate means), retreatism (withdrawing from both), or rebellion (rejecting the existing goals and means in favour of new ones).

Albert Cohen (1955) applied strain theory to juvenile gang delinquency, arguing that working-class boys who failed to meet middle-class standards in school developed an alternative status system through gang membership, inverting conventional values. Cloward and Ohlin (1960) refined this further by noting that access to illegitimate opportunity also varied by neighbourhood: some deprived communities had organised criminal enterprises that offered structured criminal careers, others had only disorganised conflict subcultures, and others produced retreatist subcultures centred on drug use.

Robert Agnew's General Strain Theory (1992) broadened Merton's framework beyond blocked economic opportunity to include any failure to achieve positively valued goals, the removal of positively valued stimuli, and exposure to negative stimuli. This version of strain theory has been tested in multiple national contexts, including surveys of youth in India, Brazil, the UK, and South Korea, and has found consistent empirical support across different cultural settings.

By the 1960s, a new current challenged criminology's assumption that crime was a fixed property of acts and people. Howard Becker's Outsiders (1963) argued that deviance is not an intrinsic quality but a label applied by social audiences with the power to define and enforce rules. Edwin Lemert distinguished primary deviance (initial rule-breaking) from secondary deviance: the reorganisation of identity and behaviour that follows from being publicly labelled a deviant. Once labelled, an individual faces exclusion from conventional roles and relationships, increasing the likelihood of further offending. Labelling theory is covered in detail in Labelling Theory and Social Reaction.

Conflict theorists went further, arguing that the criminal law itself reflects the interests of dominant social groups. Georg Vold, Richard Quinney, and later William Chambliss argued that the definitions of crime, the practices of policing, and the distribution of punishment were not neutral products of consensus but outcomes of struggles between groups with competing interests. The higher rate at which working-class and minority defendants were arrested, convicted, and incarcerated was, on this view, a function of who held power to define and enforce the law, not simply a reflection of differential offending.

From the 1980s onward, criminology diversified rather than converging on a single paradigm. Several influential theoretical currents emerged simultaneously. Gottfredson and Hirschi's General Theory of Crime (1990) argued that low self-control, established early in childhood, was the single most important predictor of offending across the life course. This biosocial approach drew on both psychological and sociological traditions. Simultaneously, life-course criminology, associated with Robert Sampson and John Laub's reanalysis of Glueck and Glueck data, showed that social bonds formed in adulthood (stable employment, marriage) could redirect offending trajectories, challenging the idea that early childhood determined everything.

Environmental criminology, including rational choice theory and routine activity theory, refocused attention on the immediate situational context of criminal events. Marcus Felson and Lawrence Cohen's routine activity theory (1979) proposed that crime occurs when a motivated offender, a suitable target, and the absence of a capable guardian converge in time and space. This framework required no theory of why offenders were motivated and instead focused on the physical and social arrangements that created or reduced criminal opportunity. These developments are explored further in Rational Choice and Routine Activity Theories.

Feminist criminology, associated with Carol Smart, Meda Chesney-Lind, and others, critiqued mainstream theories for being built on the study of male offenders and ignoring both female offending and women's disproportionate experience as victims. Critical race criminology examined how race interacted with class and gender in the operation of criminal justice in the United States, the UK, and postcolonial contexts including South Africa and India. By the early twenty-first century, criminology was genuinely pluralistic: no single theory dominated, and researchers increasingly worked across levels of analysis and drew on multiple theoretical traditions.
